KANSAS CITY, Kan. — A Turner High School student is among the victims shot at a Halloween party Monday night that left one teenager dead and six others injured.

Kansas City Police said a 17-year-old died of his injuries. An 18-year-old and five other teenagers between the ages of 15 and 16 were injured in the gunfire. Police said doctors released one of the injured teenagers, but the rest remain hospitalized.

The shooting was reported just after 9 p.m. near South 50th Street and Elmwood Avenue in the Turner area.

KCK Police Chief Karl Oakman tells FOX4 the shooting took place at a Halloween house party with 70 to 100 high school aged people. A parent was home during the party. The party was invite only through social media. Some people who were not invited showed up and were asked to leave. When those individuals were asked to leave they began shooting.

Making it more difficult, police said the shooters wore masks or some type of Halloween costumes.

No suspects are in custody at this time. As far as suspects, the only thing police know is they are looking for a dark or grey colored SUV.

“I’ve watched over the years tragedy after tragedy and these families don’t want to hear enough is enough. They are tired of saying lets give these people, victims of crime thoughts and prayers. We’ve got to do something about gun violence and terrorizing anyone else in Kansas City, Kansas, and Wyandotte County,” Mayor Tyrone Garner said.

Chief Oakman said multiple gunmen shot at the house. Detectives said they do not believe the shooting is gang-related or individual people were targeted at this time. Some of the victims were inside the house and some were outside, according to Oakman. He also said it’s believed the shooters are older than the teenagers at the party.

“This type of behavior is unacceptable and it’s not normal and it’s not OK,” Mark Dupree, Wyandotte County District Attorney, said.

The Turner School District said it will have additional support in place for students and staff who may need it beginning Wednesday morning.

“[The school district] extends our deepest sympathy to the family members and friends of students involved. Today is a professional learning day in our district so students are not present; however, our district mental health team will be on site as students return to school tomorrow,” Turner School District said in a statement.

The district also said it plans to have an increased police presence at Turner High School Wednesday morning.

Detectives are asking anyone at the party, or with video of what happened, to contact the department to help with the investigation.
